TECHNICAL FIELD

The present subject matter relates to wearable devices, e.g., eyeweardevices, and mobile devices and techniques to allow a user to createshockwaves in three-dimensional space of videos and images.

BACKGROUND

Computing devices, such as wearable devices, including portable eyeweardevices (e.g., smartglasses, headwear, and headgear); mobile devices(e.g., tablets, smartphones, and laptops); and personal computersavailable today integrate image displays and cameras. Currently, usersof computing devices can utilize photo lenses or filters to createeffects on two-dimensional (2D) photographs. Various photo decoratingapplications feature tools like stickers, emojis, and captions to edittwo-dimensional photographs.

With the advent of three-dimensional (3D) image and video content, moresophisticated manipulations and interactions to transformthree-dimensional image and video content (e.g., videos, pictures, etc.)are needed. For example, being able to manipulate and interact with thethree-dimensional image and video content to create graphical effects onthree-dimensional images and videos is desirable.

Accordingly, a need exists to enhance video and image editing effectsavailable for three-dimensional image and video content.

Reference now is made in detail to the examples illustrated in theaccompanying drawings and discussed below.

FIG. 1A is a right side view of an example hardware configuration of aneyewear device 100 utilized in a virtual shockwave creation system,which shows a right visible light camera 114B of a depth-capturingcamera to generate an initial depth image. As further described below,in the virtual shockwave creation system, a transformation function isapplied to a sequence of initial depth images of an initial video togenerate the sequence of warped shockwave images of a warped shockwavevideo. This transformation function can depend on spatial and temporalcoordinates of the initial depth images, as explained below.

Eyewear device 100, includes a right optical assembly 180B with an imagedisplay to present an initial video including initial images and warpedshockwave images of a warped shockwave video that are two-dimensional.In the example, the initial video that includes initial images orprocessed raw images that are presented to the user, but a depth videothat includes the initial depth images generated based on processed rawimages is not presented to the user. Instead, a warped version of thevisible light image is presented to the user. In the example, this depthvideo that includes the generated initial depth images is used forpurposes of calculations to generate the warped shockwave images andcreate the warped shockwave video. As shown in FIGS. 1A-B, the eyeweardevice 100 includes the right visible light camera 114B. Eyewear device100 can include multiple visible light cameras 114A-B that form apassive type of depth-capturing camera, such as stereo camera, of whichthe right visible light camera 114B is located on a right chunk 110B. Asshown in FIGS. 1C-D, the eyewear device 100 can also include a leftvisible light camera 114A. Alternatively, in the example of FIG. 2A, thedepth-capturing camera can be an active type of depth-capturing camerathat includes a single visible light camera 114B and a depth sensor (seeelement 213 of FIG. 2A).

Left and right visible light cameras 114A-B are sensitive to the visiblelight range wavelength. Each of the visible light cameras 114A-B have adifferent frontward facing field of view which are overlapping to allowthree-dimensional depth images to be generated, for example, rightvisible light camera 114B has the depicted right field of view 111B.Generally, a “field of view” is the part of the scene that is visiblethrough the camera at a particular position and orientation in space.Objects or object features outside the field of view 111A-B when theimage is captured by the visible light camera are not recorded in a rawimage (e.g., photograph or picture). The field of view describes anangle range or extent which the image sensor of the visible light camera114A-B picks up electromagnetic radiation of a given scene in a capturedimage of the given scene. Field of view can be expressed as the angularsize of the view cone, i.e., an angle of view. The angle of view can bemeasured horizontally, vertically, or diagonally.

In an example, visible light cameras 114A-B have a field of view with anangle of view between 15° to 30°, for example 24°, and have a resolutionof 480×480 pixels. The “angle of coverage” describes the angle rangethat a lens of visible light cameras 114A-B or infrared camera 220 (seeFIG. 2A) can effectively image. Typically, the image circle produced bya camera lens is large enough to cover the film or sensor completely,possibly including some vignetting toward the edge. If the angle ofcoverage of the camera lens does not fill the sensor, the image circlewill be visible, typically with strong vignetting toward the edge, andthe effective angle of view will be limited to the angle of coverage.

Examples of such visible lights camera 114A-B include a high-resolutioncomplementary metal-oxide-semiconductor (CMOS) image sensor and a videographic array (VGA) camera, such as 640p (e.g., 640×480 pixels for atotal of 0.3 megapixels), 720p, or 1080p. As used herein, the term“overlapping” when referring to field of view means the matrix of pixelsin the generated raw image(s) or infrared image of a scene overlap by30% or more. As used herein, the term “substantially overlapping” whenreferring to field of view means the matrix of pixels in the generatedraw image(s) or infrared image of a scene overlap by 50% or more.

Image sensor data from the visible light cameras 114A-B are capturedalong with geolocation data, digitized by an image processor, and storedin a memory. The captured left and right raw images captured byrespective visible light cameras 114A-B are in the two-dimensional spacedomain and comprise a matrix of pixels on a two-dimensional coordinatesystem that includes an X axis for horizontal position and a Y axis forvertical position. Each pixel includes a color attribute (e.g., a redpixel light value, a green pixel light value, and/or a blue pixel lightvalue); and a position attribute (e.g., an X location coordinate and a Ylocation coordinate).

To provide stereoscopic vision, visible light cameras 114A-B may becoupled to an image processor (element 912 of FIG. 9) for digitalprocessing along with a timestamp in which the image of the scene iscaptured. Image processor 912 includes circuitry to receive signals fromthe visible light cameras 114A-B and process those signals from thevisible light camera 114 into a format suitable for storage in thememory. The timestamp can be added by the image processor or otherprocessor, which controls operation of the visible light cameras 114A-B.Visible light cameras 114A-B allow the depth-capturing camera tosimulate human binocular vision. Depth-capturing camera provides theability to reproduce three-dimensional images based on two capturedimages from the visible light cameras 114A-B having the same timestamp.Such three-dimensional images allow for an immersive life-likeexperience, e.g., for virtual reality or video gaming. Three-dimensionaldepth videos may be produced by stitching together a sequence ofthree-dimensional depth images with associated time coordinates for apresentation time in a depth video.

For stereoscopic vision, a pair of raw red, green, and blue (RGB) imagesare captured of a scene at a given moment in time—one image for each ofthe left and right visible light cameras 114A-B. When the pair ofcaptured raw images from the frontward facing left and right field ofviews 111A-B of the left and right visible light cameras 114A-B areprocessed (e.g., by the image processor), depth images are generated,and the generated depth images can be perceived by a user on the opticalassembly 180A-B or other image display(s) (e.g., of a mobile device).The generated depth images are in the three-dimensional space domain andcan comprise a matrix of vertices on a three-dimensional locationcoordinate system that includes an X axis for horizontal position (e.g.,length), a Y axis for vertical position (e.g., height), and a Z axis fora depth position (e.g., distance). A depth video further associates eachof a sequence of generated depth images with a time coordinate on a time(T) axis for a presentation time in the depth video (e.g., each depthimage includes spatial components as well as a temporal component). Thedepth video can further include an audio component (e.g., audio track orstream), which may be captured by a microphone. Each vertex includes aposition attribute (e.g., a red pixel light value, a green pixel lightvalue, and/or a blue pixel light value); a position attribute (e.g., anX location coordinate, a Y location coordinate, and a Z locationcoordinate); a texture attribute, and/or a reflectance attribute. Thetexture attribute quantifies the perceived texture of the depth image,such as the spatial arrangement of color or intensities in a region ofvertices of the depth image.

Generally, perception of depth arises from the disparity of a given 3Dpoint in the left and right raw images captured by visible light cameras114A-B. Disparity is the difference in image location of the same 3Dpoint when projected under perspective of the visible light cameras114A-B (d=x_(left)−x_(right)). For visible light cameras 114A-B withparallel optical axes, focal length f, baseline b, and correspondingimage points (x_(left), y_(left)) and (x_(right), y_(right)), thelocation of a 3D point (Z axis location coordinate) can be derivedutilizing triangulation which determines depth from disparity.Typically, depth of the 3D point is inversely proportional to disparity.A variety of other techniques can also be used. Generation ofthree-dimensional depth images and warped shockwave images is explainedin more detail later.

In an example, a virtual shockwave creation system includes the eyeweardevice 100. The eyewear device 100 includes a frame 105 and a lefttemple 110A extending from a left lateral side 170A of the frame 105 anda right temple 110B extending from a right lateral side 170B of theframe 105. Eyewear device 100 further includes a depth-capturing camera.The depth-capturing camera includes: (i) at least two visible lightcameras with overlapping fields of view; or (ii) a least one visiblelight camera 114A-B and a depth sensor (element 213 of FIG. 2A). In oneexample, the depth-capturing camera includes a left visible light camera114A with a left field of view 111A connected to the frame 105 or theleft temple 110A to capture a left image of the scene. Eyewear device100 further includes a right visible light camera 114B connected to theframe 105 or the right temple 110B with a right field of view 111B tocapture (e.g., simultaneously with the left visible light camera 114A) aright image of the scene which partially overlaps the left image.

Virtual shockwave creation system further includes a computing device,such as a host computer (e.g., mobile device 990 of FIGS. 9-10) coupledto eyewear device 100 over a network. The virtual shockwave creationsystem further includes an image display (optical assembly 180A-B ofeyewear device; image display 1080 of mobile device 990 of FIG. 10) forpresenting (e.g., displaying) a video including images. Virtualshockwave creation system further includes an image display driver(element 942 of eyewear device 100 of FIG. 9; element 1090 of mobiledevice 990 of FIG. 10) coupled to the image display (optical assembly180A-B of eyewear device; image display 1080 of mobile device 990 ofFIG. 10) to control the image display to present the initial video.

In some examples, user input is received to indicate that the userdesires shockwaves to be applied to the various initial depth imagesfrom the initial video. For example, virtual shockwave creation systemfurther includes a user input device to receive a shockwave effectselection from a user to apply shockwaves to the presented initialvideo. Examples of user input devices include a touch sensor (element991 of FIG. 9 for the eyewear device 100), a touch screen display(element 1091 of FIG. 10 for the mobile device 1090), and a computermouse for a personal computer or a laptop computer. Virtual shockwavecreation system further includes a processor (element 932 of eyeweardevice 100 of FIG. 9; element 1030 of mobile device 990 of FIG. 10)coupled to the eyewear device 100 and the depth-capturing camera.Virtual shockwave creation system further includes a memory (element 934of eyewear device 100 of FIG. 9; elements 1040A-B of mobile device 990of FIG. 10) accessible to the processor, and shockwave creationprogramming in the memory (element 945 of eyewear device 100 of FIG. 9;element 945 of mobile device 990 of FIG. 10), for example in the eyeweardevice 100 itself, mobile device (element 990 of FIG. 9), or anotherpart of the virtual shockwave creation system (e.g., server system 998of FIG. 9). Execution of the programming (element 945 of FIG. 9) by theprocessor (element 932 of FIG. 9) configures the eyewear device 100 togenerate, via the depth-capturing camera, the initial depth images fromthe initial images 957A-N in the initial video. The initial images957A-N are in two-dimensional space, for example raw images 858A-B orprocessed raw images 858A-B after rectification. Each of the initialdepth images is associated with a time coordinate on a time (T) axis fora presentation time, for example based, on initial images 957A-B in theinitial video. The initial depth image is formed of a matrix ofvertices. Each vertex represents a pixel in a three-dimensional scene.Each vertex has a position attribute. The position attribute of eachvertex is based on a three-dimensional location coordinate system andincludes an X location coordinate on an X axis for horizontal position,a Y location coordinate on a Y axis for vertical position, and a Zlocation coordinate on a Z axis for a depth position.

Execution of the shockwave creation programming (element 945 of FIG. 10)by the processor (element 1030 of FIG. 10) configures the mobile device(element 990 of FIG. 10) of the virtual shockwave creation system toperform the following functions. Mobile device (element 990 of FIG. 10)presents, via the image display (element 1080 of FIG. 10), the initialvideo. Mobile device (element 990 of FIG. 10) receives, via the userinput device (element 1091 of FIG. 10), the shockwave effect selectionfrom the user to apply shockwaves to the presented initial video. Inresponse to receiving the shockwave effect selection, based on, atleast, the associated time coordinate of each of the initial depthimages, mobile device (element 990 of FIG. 10) applies to vertices ofeach of the initial depth images, a transformation function. Thetransformation function can transform a respective shockwave region ofvertices grouped together along the Z axis based on, at least, theassociated time coordinate of the respective initial depth image. Therespective transformation function moves a respective Y locationcoordinate of vertices in the respective shockwave region of verticesvertically upwards or downwards on the Y axis, which appears as a depthwarping effect. In one example, based on the X, Y, and/or Z locationcoordinates of the vertices and the associated time coordinate, thetransformation function transforms all the vertices of the initial depthimages. In one example, the transformation function is an equation newY=func (X, old Y,Z,T), which does not depend on the X locationcoordinate. An example transformation function where the wave isadvancing in the Z direction (so this specific function does not dependon X) is new Y=f (Y,Z,t)=Y+200/(exp(20/3−abs(Z−300*t)/150)+1)−200. Thetransformation is applied per-vertex, where the transformation relays onboth space and time. Applying the transformation function creates a newmodified set of vertices or a three-dimensional image without a depthmap.

Mobile device (element 990 of FIG. 10) generates, for each of theinitial depth images, a respective shockwave depth image by applying thetransformation function to the respective initial depth image. Mobiledevice (element 990 of FIG. 10) can generate a respective shockwavedepth image by applying the transformation function to the positionattribute of the vertices in a respective shockwave region of verticesof the respective initial depth image. Mobile device (element 990 ofFIG. 10) creates, a warped shockwave video including the sequence of thegenerated warped shockwave images. Mobile device (element 990 of FIG.10) presents, via the image display (image display 1080 of FIG. 10), thewarped shockwave video. Mobile device (element 990 of FIG. 10) presents,via the image display (image display 1080 of FIG. 10), the warpedshockwave video. Various shockwave creation programming (element 945 ofFIGS. 9-10) functions described herein may be implemented within otherparts of the virtual shockwave creation system, such as the eyeweardevice 100 or another host computer besides mobile device (element 990of FIG. 10), such as a server system (element 998 of FIG. 9).

In some examples, the received shockwave effect selection generates ashockwave creation photo filter effect, which is applied as thetransformation function to the initial video in response to fingerswiping across a touch screen display (e.g., combined image display 1080and user input device 1091). The warped shockwave video with theshockwave creation photo filter effect may then be shared with friendsvia a chat application executing on the mobile device (element 990 ofFIG. 10) by transmission over a network.

FIG. 1B is a top cross-sectional view of a right chunk 110B of theeyewear device 100 of FIG. 1A depicting the right visible light camera114B of the depth-capturing camera, and a circuit board. FIG. 1C is aleft side view of an example hardware configuration of an eyewear device100 of FIG. 1A, which shows a left visible light camera 114A of thedepth-capturing camera. FIG. 1D is a top cross-sectional view of a leftchunk 110A of the eyewear device of FIG. 1C depicting the left visiblelight camera 114A of the depth-capturing camera, and a circuit board.Construction and placement of the left visible light camera 114A issubstantially similar to the right visible light camera 114B, except theconnections and coupling are on the left lateral side 170A. As shown inthe example of FIG. 1B, the eyewear device 100 includes the rightvisible light camera 114B and a circuit board, which may be a flexibleprinted circuit board (PCB) 140B. The right hinge 226B connects theright chunk 110B to a right temple 125B of the eyewear device 100. Insome examples, components of the right visible light camera 114B, theflexible PCB 140B, or other electrical connectors or contacts may belocated on the right temple 125B or the right hinge 226B.

The right chunk 110B includes chunk body 211 and a chunk cap, with thechunk cap omitted in the cross-section of FIG. 1B. Disposed inside theright chunk 110B are various interconnected circuit boards, such as PCBsor flexible PCBs, that include controller circuits for right visiblelight camera 114B, microphone(s), low-power wireless circuitry (e.g.,for wireless short range network communication via Bluetooth™),high-speed wireless circuitry (e.g., for wireless local area networkcommunication via WiFi).

The right visible light camera 114B is coupled to or disposed on theflexible PCB 240 and covered by a visible light camera cover lens, whichis aimed through opening(s) formed in the frame 105. For example, theright rim 107B of the frame 105 is connected to the right chunk 110B andincludes the opening(s) for the visible light camera cover lens. Theframe 105 includes a front-facing side configured to face outwards awayfrom the eye of the user. The opening for the visible light camera coverlens is formed on and through the front-facing side. In the example, theright visible light camera 114B has an outwards facing field of view111B with a line of sight or perspective of the right eye of the user ofthe eyewear device 100. The visible light camera cover lens can also beadhered to an outwards facing surface of the right chunk 110B in whichan opening is formed with an outwards facing angle of coverage, but in adifferent outwards direction. The coupling can also be indirect viaintervening components.

Left (first) visible light camera 114A is connected to a left imagedisplay of left optical assembly 180A to capture a left eye viewed sceneobserved by a wearer of the eyewear device 100 in a left raw image.Right (second) visible light camera 114B is connected to a right imagedisplay of right optical assembly 180B to capture a right eye viewedscene observed by the wearer of the eyewear device 100 in a right rawimage. The left raw image and the right raw image partially overlap topresent a three-dimensional observable space of a generated depth image.

Flexible PCB 140B is disposed inside the right chunk 110B and is coupledto one or more other components housed in the right chunk 110B. Althoughshown as being formed on the circuit boards of the right chunk 110B, theright visible light camera 114B can be formed on the circuit boards ofthe left chunk 110A, the temples 125A-B, or frame 105.

FIG. 2A is a right side view of another example hardware configurationof an eyewear device 100 utilized in the virtual shockwave creationsystem. As shown, the depth-capturing camera includes a left visiblelight camera 114A and a depth sensor 213 on a frame 105 to generate aninitial depth image of a sequence of initial depth images (e.g., in aninitial video). Instead of utilizing at least two visible light cameras114A-B to generate the initial depth image, here a single visible lightcamera 114A and the depth sensor 213 are utilized to generate depthimages, such as the initial depth images. As in the example of FIGS.1A-D, shockwave effect selection from a user is applied to initial depthimages from the initial video to generate warped shockwave images ofwarped shockwave video. The infrared camera 220 of the depth sensor 213has an outwards facing field of view that substantially overlaps withthe left visible light camera 114A for a line of sight of the eye of theuser. As shown, the infrared emitter 215 and the infrared camera 220 areco-located on the upper portion of the left rim 107A with the leftvisible light camera 114A.

In the example of FIG. 2A, the depth sensor 213 of the eyewear device100 includes an infrared emitter 215 and an infrared camera 220 whichcaptures an infrared image. Visible light cameras 114A-B typicallyinclude a blue light filter to block infrared light detection, in anexample, the infrared camera 220 is a visible light camera, such as alow resolution video graphic array (VGA) camera (e.g., 640×480 pixelsfor a total of 0.3 megapixels), with the blue filter removed. Theinfrared emitter 215 and the infrared camera 220 are co-located on theframe 105, for example, both are shown as connected to the upper portionof the left rim 107A. As described in further detail below, the frame105 or one or more of the left and right chunks 110A-B include a circuitboard that includes the infrared emitter 215 and the infrared camera220. The infrared emitter 215 and the infrared camera 220 can beconnected to the circuit board by soldering, for example.

Other arrangements of the infrared emitter 215 and infrared camera 220can be implemented, including arrangements in which the infrared emitter215 and infrared camera 220 are both on the right rim 107A, or indifferent locations on the frame 105, for example, the infrared emitter215 is on the left rim 107B and the infrared camera 220 is on the rightrim 107B. However, the at least one visible light camera 114A and thedepth sensor 213 typically have substantially overlapping fields of viewto generate three-dimensional depth images. In another example, theinfrared emitter 215 is on the frame 105 and the infrared camera 220 ison one of the chunks 110A-B, or vice versa. The infrared emitter 215 canbe connected essentially anywhere on the frame 105, left chunk 110A, orright chunk 110B to emit a pattern of infrared in the light of sight ofthe eye of the user. Similarly, the infrared camera 220 can be connectedessentially anywhere on the frame 105, left chunk 110A, or right chunk110B to capture at least one reflection variation in the emitted patternof infrared light of a three-dimensional scene in the light of sight ofthe eye of the user.

The infrared emitter 215 and infrared camera 220 are arranged to faceoutwards to pick up an infrared image of a scene with objects or objectfeatures that the user wearing the eyewear device 100 observes. Forexample, the infrared emitter 215 and infrared camera 220 are positioneddirectly in front of the eye, in the upper part of the frame 105 or inthe chunks 110A-B at either ends of the frame 105 with a forward facingfield of view to capture images of the scene which the user is gazingat, for measurement of depth of objects and object features.

In one example, the infrared emitter 215 of the depth sensor 213 emitsinfrared light illumination in the forward facing field of view of thescene, which can be near-infrared light or other short-wavelength beamof low-energy radiation. Alternatively, or additionally, the depthsensor 213 may include an emitter that emits other wavelengths of lightbesides infrared and the depth sensor 213 further includes a camerasensitive to that wavelength that receives and captures images with thatwavelength. As noted above, the eyewear device 100 is coupled to aprocessor and a memory, for example in the eyewear device 100 itself oranother part of the virtual shockwave creation system. Eyewear device100 or the virtual shockwave creation system can subsequently processthe captured infrared image during generation of three-dimensional depthimages of the depth videos, such as the initial depth images from theinitial video.

FIGS. 2B-C are rear views of example hardware configurations of theeyewear device 100, including two different types of image displays.Eyewear device 100 is in a form configured for wearing by a user, whichare eyeglasses in the example. The eyewear device 100 can take otherforms and may incorporate other types of frameworks, for example, aheadgear, a headset, or a helmet.

In the eyeglasses example, eyewear device 100 includes a frame 105including a left rim 107A connected to a right rim 107B via a bridge 106adapted for a nose of the user. The left and right rims 107A-B includerespective apertures 175A-B which hold a respective optical element180A-B, such as a lens and a display device. As used herein, the termlens is meant to cover transparent or translucent pieces of glass orplastic having curved and/or flat surfaces that cause light toconverge/diverge or that cause little or no convergence or divergence.

Although shown as having two optical elements 180A-B, the eyewear device100 can include other arrangements, such as a single optical element ormay not include any optical element 180A-B depending on the applicationor intended user of the eyewear device 100. As further shown, eyeweardevice 100 includes a left chunk 110A adjacent the left lateral side170A of the frame 105 and a right chunk 110B adjacent the right lateralside 170B of the frame 105. The chunks 110A-B may be integrated into theframe 105 on the respective sides 170A-B (as illustrated) or implementedas separate components attached to the frame 105 on the respective sides170A-B. Alternatively, the chunks 110A-B may be integrated into temples(not shown) attached to the frame 105.

In one example, the image display of optical assembly 180A-B includes anintegrated image display. As shown in FIG. 2B, the optical assembly180A-B includes a suitable display matrix 170 of any suitable type, suchas a liquid crystal display (LCD), an organic light-emitting diode(OLED) display, or any other such display. The optical assembly 180A-Balso includes an optical layer or layers 176, which can include lenses,optical coatings, prisms, mirrors, waveguides, optical strips, and otheroptical components in any combination. The optical layers 176A-N caninclude a prism having a suitable size and configuration and including afirst surface for receiving light from display matrix and a secondsurface for emitting light to the eye of the user. The prism of theoptical layers 176A-N extends over all or at least a portion of therespective apertures 175A-B formed in the left and right rims 107A-B topermit the user to see the second surface of the prism when the eye ofthe user is viewing through the corresponding left and right rims107A-B. The first surface of the prism of the optical layers 176A-Nfaces upwardly from the frame 105 and the display matrix overlies theprism so that photons and light emitted by the display matrix impingethe first surface. The prism is sized and shaped so that the light isrefracted within the prism and is directed towards the eye of the userby the second surface of the prism of the optical layers 176A-N. In thisregard, the second surface of the prism of the optical layers 176A-N canbe convex to direct the light towards the center of the eye. The prismcan optionally be sized and shaped to magnify the image projected by thedisplay matrix 170, and the light travels through the prism so that theimage viewed from the second surface is larger in one or more dimensionsthan the image emitted from the display matrix 170.

In another example, the image display device of optical assembly 180A-Bincludes a projection image display as shown in FIG. 2C. The opticalassembly 180A-B includes a laser projector 150, which is a three-colorlaser projector using a scanning mirror or galvanometer. Duringoperation, an optical source such as a laser projector 150 is disposedin or on one of the temples 125A-B of the eyewear device 100. Opticalassembly 180A-B includes one or more optical strips 155A-N spaced apartacross the width of the lens of the optical assembly 180A-B or across adepth of the lens between the front surface and the rear surface of thelens.

As the photons projected by the laser projector 150 travel across thelens of the optical assembly 180A-B, the photons encounter the opticalstrips 155A-N. When a particular photon encounters a particular opticalstrip, the photon is either redirected towards the user's eye, or itpasses to the next optical strip. A combination of modulation of laserprojector 150, and modulation of optical strips, may control specificphotons or beams of light. In an example, a processor controls opticalstrips 155A-N by initiating mechanical, acoustic, or electromagneticsignals. Although shown as having two optical assemblies 180A-B, theeyewear device 100 can include other arrangements, such as a single orthree optical assemblies, or the optical assembly 180A-B may havearranged different arrangement depending on the application or intendeduser of the eyewear device 100.

As further shown in FIGS. 2B-C, eyewear device 100 includes a left chunk110A adjacent the left lateral side 170A of the frame 105 and a rightchunk 110B adjacent the right lateral side 170B of the frame 105. Thechunks 110A-B may be integrated into the frame 105 on the respectivelateral sides 170A-B (as illustrated) or implemented as separatecomponents attached to the frame 105 on the respective sides 170A-B.Alternatively, the chunks 110A-B may be integrated into temples 125A-Battached to the frame 105.

In one example, the image display includes a first (left) image displayand a second (right) image display. Eyewear device 100 includes firstand second apertures 175A-B which hold a respective first and secondoptical assembly 180A-B. The first optical assembly 180A includes thefirst image display (e.g., a display matrix 170A of FIG. 2B; or opticalstrips 155A-N′ and a projector 150A of FIG. 2C). The second opticalassembly 180B includes the second image display e.g., a display matrix170B of FIG. 2B; or optical strips 155A-N″ and a projector 150B of FIG.2C).

Theinfrared camera 220 is disposed on the flexible PCB 340 and covered byan infrared camera cover lens 445. For example, the infrared camera 220is reflowed to the back of the flexible PCB 340. Reflowing attaches theinfrared camera 220 to electrical contact pad(s) formed on the back ofthe flexible PCB 340 by subjecting the flexible PCB 340 to controlledheat which melts a solder paste to connect the two components. In oneexample, reflowing is used to surface mount the infrared camera 220 onthe flexible PCB 340 and electrically connect the two components.However, it should be understood that through-holes can be used toconnect leads from the infrared camera 220 to the flexible PCB 340 viainterconnects, for example.

Multiple layers of the eyewear device 100 areillustrated in the cross-section of FIG. 6, as shown the frame 105includes the frame front 330 and the frame back 335. The flexible PCB340 is disposed on the frame back 335 and connected to the frame front330. The infrared emitter 215 is disposed on the flexible PCB 340 andcovered by an infrared emitter cover lens 645. For example, the infraredemitter 215 is reflowed to the back of the flexible PCB 340. Reflowingattaches the infrared emitter 215 to contact pad(s) formed on the backof the flexible PCB 340 by subjecting the flexible PCB 340 to controlledheat which melts a solder paste to connect the two components. In oneexample, reflowing is used to surface mount the infrared emitter 215 onthe flexible PCB 340 and electrically connect the two components.However, it should be understood that through-holes can be used toconnect leads from the infrared emitter 215 to the flexible PCB 340 viainterconnects, for example.

The frame front 330 includes an infrared emitter opening 650 for theinfrared emitter cover lens 645.

FIG. 7 depicts an example of an emitted pattern of infrared light 781emitted by an infrared emitter 215 of the depth sensor 213. As shown,reflection variations of the emitted pattern of infrared light 782 arecaptured by the infrared camera 220 of the depth sensor 213 of theeyewear device 100 as an infrared image. The reflection variations ofthe emitted pattern of infrared light 782 is utilized to measure depthof pixels in a raw image (e.g., left raw image) to generatethree-dimensional depth images, such as the initial depth images of asequence of initial depth images (e.g., in an initial video).

Depth sensor 213 in the example includes the infrared emitter 215 toproject a pattern of infrared light and the infrared camera 220 tocapture infrared images of distortions of the projected infrared lightby objects or object features in a space, shown as scene 715 beingobserved by the wearer of the eyewear device 100. The infrared emitter215, for example, may blast infrared light 781 which falls on objects orobject features within the scene 715 like a sea of dots. In someexamples, the infrared light is emitted as a line pattern, a spiral, ora pattern of concentric rings or the like. Infrared light is typicallynot visible to the human eye. The infrared camera 220 is similar to astandard red, green, and blue (RGB) camera but receives and capturesimages of light in the infrared wavelength range. For depth sensing, theinfrared camera 220 is coupled to an image processor (element 912 ofFIG. 9) and the shockwave creation programming (element 945) that judgetime of flight based on the captured infrared image of the infraredlight. For example, the distorted dot pattern 782 in the capturedinfrared image can then be processed by an image processor to determinedepth from the displacement of dots. Typically, nearby objects or objectfeatures have a pattern with dots spread further apart and far awayobjects have a denser dot pattern. It should be understood that theforegoing functionality can be embodied in programming instructions ofshockwave creation programming or application (element 945) found in oneor more components of the system.

As shown, eyewear device 100 includes an orientation sensor, whichincludes, for example, an inertial measurement unit (IMU) 972 asdepicted. Generally, an inertial measurement unit 972 is an electronicdevice that measures and reports a body's specific force, angular rate,and sometimes the magnetic field surrounding the body, using acombination of accelerometers and gyroscopes, sometimes alsomagnetometers. In this example, the inertial measurement unit 972determines a head orientation of a wearer of the eyewear device 100which correlates to a camera orientation of the depth-capturing cameraof the eyewear device 100 when the associated depth image is captured,which is utilized in transforming a respective shockwave region ofvertices 966A-N, as explained below. The inertial measurement unit 972works by detecting linear acceleration using one or more accelerometersand rotational rate using one or more gyroscopes. Typical configurationsof inertial measurement units contain one accelerometer, gyro, andmagnetometer per axis for each of the three axes: horizontal axis forleft-right movement (X), vertical axis (Y) for top-bottom movement, anddepth or distance axis for up-down movement (Z). The gyroscope detectsthe gravity vector. The magnetometer defines the rotation in themagnetic field (e.g., facing south, north, etc.) like a compass whichgenerates a heading reference. The three accelerometers detectacceleration along the horizontal (X), vertical (Y), and depth (Z) axesdefined above, which can be defined relative to the ground, the eyeweardevice 100, the depth-capturing camera, or the user wearing the eyeweardevice 100.

The head orientationmeasurements are utilized to determine alignment of the depth-capturingcamera, which can be used to identify a floor plane of the initial depthimages 961A-N. In certain applications of IMUs, the principal axes arereferred to as pitch, roll, and yaw axes.

A flowchartoutlining functions which can be implemented in the shockwave creationprogramming 945 is shown in FIG. 11. Memory 934 further includes ashockwave effect selection 962 received by the user input device 991,which is user input indicating that application of the shockwave effecton the initial video 960 is desired. In some examples, the shockwaveeffect selection 962 may impact the strength or degree to which theshockwaves imparted on the initial video 960 warp the initial depthimages 961A-N (e.g., by adjusting the amplitude or frequency of theshockwaves). Memory 934 further includes transformation matrices 965,shockwave regions of vertices 966A-N, affinity matrices 968A-N, wavepattern 971, left and right rectified images 969A-B (e.g., to removevignetting towards the end of the lens), and an image disparity 970, allof which are generated during image processing of the initial depthimages 961A-N from the initial video 960 to generate respective warpedshockwave images 967A-N of the warped shockwave video 964.

Each of the initial depthimages 961A-N is associated with a time coordinate on a time (T) axisfor a presentation time, based on, for example, initial images 957A-N,in the initial video 960. Each of the initial depth images 961A-N isformed of a matrix of vertices. Each vertex represents a pixel in athree-dimensional scene 715. Each vertex has a position attribute. Theposition attribute of each vertex is based on a three-dimensionallocation coordinate system and includes an X location coordinate on an Xaxis for horizontal position, a Y location coordinate on a Y axis forvertical position, and a Z location coordinate on a Z axis for a depthposition. Each vertex further includes one or more of a color attribute,a texture attribute, or a reflectance attribute.

Virtual shockwave creation system 900 presents, via the image display180A-B, 1080 the initial video 960. Eyewear device 100 receives, via theuser input device 991, 1091, a shockwave effect selection from the userto apply shockwaves to the presented initial video 960. Virtualshockwave creation system 900 receives, via the user input device 991,1091, the shockwave effect selection 962 from the user to applyshockwaves to the presented initial video 960.

In response to receiving the shockwave effect selection 962, based on,at least, the associated time coordinate 963A-N of each of the initialdepth images 961A-N, virtual shockwave creation system 900 applies tovertices of each of the initial depth images 961A-N, a respectivetransformation function 965.

Execution of the shockwave creation programming945 by the first processor 932 configures the eyewear device 100 toperform the function to generate, via the depth-capturing camera, theinitial depth images 961A-N from the initial video 960 and associatedtime coordinates 963A-N.

The virtual shockwave creation system 900 further comprises a hostcomputer, such as the mobile device 990, coupled to the eyewear device100 over the network 925 or 937. The host computer includes a secondnetwork communication interface 1010 or 1020 for communication over thenetwork 925 or 937, the second processor 1030 coupled to the secondnetwork communication interface 1010 or 1020, and the second memory1040A accessible to the second processor 1030. Host computer furtherincludes shockwave creation programming 945 in the second memory 1040A.

Execution of the shockwave creation programming 945 by the secondprocessor 1030 configures the host computer to perform the functions toreceive, via the second network communication interface 1010 or 1020,the initial video 960 over the network from the eyewear device 100.Execution of the shockwave creation programming 945 by the secondprocessor 1030 configures the host computer to present, via the imagedisplay 1080, the initial video 960. Execution of the shockwave creationprogramming 945 by the second processor 1030 configures the hostcomputer to receive, via the user input device 1091 (e.g., touch screenor a computer mouse), the shockwave effect selection 962 from the userto apply shockwaves to the presented initial video 960. Execution of theshockwave creation programming 945 by the second processor 1030configures the host computer to in response to receiving the shockwaveeffect selection 962, based on, at least, the associated time coordinate963A-N of each of the initial depth images 961A-N, 965 generate, foreach of the initial depth images 961A-N, the respective shockwave depthimage 967A-N by applying the transformation function 965 to vertices ofthe respective initial depth image 961A-N based on, at least, the Y andZ location coordinates and the associated time coordinate 963A-N.Execution of the shockwave creation programming 945 by the secondprocessor 1030 configures the host computer to create, the warpedshockwave video 964 including the sequence of the generated warpedshockwave images 967A-N. Execution of the shockwave creation programming945 by the second processor 1030 configures the host computer topresent, via the image display 1080, the warped shockwave video 964.

In the example, the eyewear device 100 further includes an inertialmeasurement unit 972. Execution of the programming by the processorconfigures the virtual shockwave creation system 900 to perform thefollowing functions. Measure, via the inertial measurement unit 972, arotation of the eyewear device 100 during capture of the initial depthimages 961A-N by the depth-capturing camera. For each of the initialdepth images 961A-N, determine a respective rotation matrix 973A-N toadjust X, Y, and Z location coordinates of the vertices based on themeasured rotation of the eyewear device 100 during capture. Therespective warped shockwave 967A-N is generated by applying the rotationmatrix 973A-N to vertices of the respective initial depth image 961A-Nand then applying the transformation function 965.

In one example, applying the transformation function 965 to each initialdepth image moves the respective Y location coordinate of vertices inthe respective shockwave region of vertices 966A-N vertically upwards ordownwards on the Y axis to vertically fluctuate or oscillate therespective shockwave region of vertices 966A-N. The function ofgenerating, for each of the initial depth images 961A-N, the respectiveshockwave depth image 967A-N by applying the transformation function 965to the respective initial depth image 961A-N vertically fluctuates oroscillates the respective shockwave region of vertices 966A-N and storesthe respective initial depth image 961A-N with the vertical fluctuationsor oscillations as the respective shockwave depth image 967A-N.

In some examples, the transformation function 965 moves the respective Ylocation coordinate of vertices in the respective shockwave region ofvertices 966A-N vertically upwards or downwards based on a wave pattern971. The wave pattern 971 provides an appearance of a rolling waveradially from the depth-capturing camera, radially from an objectemitting a shockwave, or along the Z axis of the warped shockwave images967A-N of the warped shockwave video 964. This can provide a visualeffect that The Incredible Hulk® is moving around the scenes of thewarped shockwave images 967A-N of the warped shockwave video 964 bymanifesting itself with the ground shaking as in an earthquake. Eachinitial depth image 961A-N includes a starting depth position on the Zaxis corresponding to a minimum depth of the respective initial depthimage 961A-N and an ending depth position on the Z axis having a maximumdepth of the respective initial depth image 961A-N. The function oftransforming the respective shockwave region of vertices 966A-N alongthe Z axis based on, at least, the associated time coordinate 963A-N ofthe respective initial depth image 961A-N further includes the followingfunctions. For each of the sequence of the initial depth images 961A-N,iteratively transforming the respective shockwave region of vertices966A-N along the Z axis based on progression of the associated timecoordinate 963A-N from the starting depth position to the ending depthposition. In response to reaching the ending depth position of the Zaxis or exceeding a restart time interval of the wave pattern 971,restarting the iterative selection of the respective shockwave region966A-N at the starting depth position.

In an example, an earlier initial depth image 961A is associated with anearlier time coordinate 963A on the time (T) axis for an earlierpresentation time in the initial video 960. An intermediate initialdepth image 961B is associated with an intermediate time coordinate 963Bon the time (T) axis for an intermediate presentation time after theearlier presentation time in the initial video 960. The function oftransforming the respective shockwave region of vertices 966A-N alongthe Z axis based on, at least, the associated time coordinate 963A-N ofthe respective initial depth image 961A-N includes the followingfunctions. Transforming a near range shockwave region of vertices 966Awith nearer depth positions grouped contiguously together along the Zaxis for the earlier initial depth image 961A based on the earlier timecoordinate 963A. Transforming an intermediate range shockwave region ofvertices 966B with intermediate depth positions grouped contiguouslytogether along the Z axis for the intermediate initial depth image 961Bbased on the intermediate time coordinate. The near range shockwaveregion of vertices 966A is closer in depth along the Z axis than theintermediate range shockwave region of vertices 966B.

In the example, a later initial depth image 961C is associated with alater time coordinate 963C on the time (T) axis for a later presentationtime after the intermediate presentation time of the intermediateinitial depth image 961B in the initial video 960. The function oftransforming the respective shockwave region of vertices 966A-N alongthe Z axis based on, at least, the associated time coordinate 963A-N ofthe respective initial depth image 961A-N further includes transforminga far range shockwave region of vertices 966C with farther depthpositions grouped contiguously together along the Z axis for the laterinitial depth image 961C based on the later time coordinate 963C. Thefar range shockwave region of vertices 966C is farther in depth alongthe Z axis than the intermediate range shockwave region of vertices966C.

If the transformation matrices 965 are applied to a single vertex, aspike or pinch will occur. In order to generate a smooth (curvy) warpedshockwave images 967A-B, the affinity matrices 968A-N are computed as aregion of influence. For example, a polygon with a specific width andlength or a circle can be set with a specific radius. Then the amount oraffinity of each vertex to the polygon or the center of the circle (likea segmentation) is computed (e.g., utilizing edge detection), so eachvertex has a weight between zero and one as to how the vertex isinfluenced by the transformation function 965. Essentially each vertexmoves according to this weight. If the weight is one, the vertex istransformed according to the transformation function 965. If the weightis zero, the vertex does not move. If the weight is one-half, the vertexwill come halfway between the original position and the transformedposition.

Hence, execution of the shockwave creation programming 945 by theprocessor 932, 1030 configures the virtual shockwave creation system 900to perform functions, including functions to compute a respectiveaffinity matrix 968A-N for the vertices of the respective initial depthimage 961A-N that determines an influence weight of the transformationfunction 965 on each of the vertices in the respective shockwave regionof vertices 966A-N. The influence weight is based on, at least, thevertical position of the vertex. The function of generating, for each ofthe initial depth images 961A-N, the respective shockwave depth image967A-N by applying the transformation function 965 to the respectiveinitial depth image 961A-N is further based on the computed respectiveaffinity matrix 968A-N. The influence weight is greater as a height ofthe vertex relative to a floor plane of the respective initial depthimage 961A-N decreases such that the transformation function 965 movesthe Y location coordinate of the vertex vertically upwards on the Y axisto a greater extent. The influence weight is lower as the height of thevertex relative to the floor plane increases such that thetransformation function 965 moves the Y location coordinate of thevertex vertically upwards on the Y axis to a lesser extent.

In an example, virtual shockwave creation system 900 further includes aninertial measurement unit 872 like that shown for the eyewear device 100in FIG. 9 and the mobile device 990 in FIG. 10. The function oftransforming the respective shockwave region of vertices 966A-N alongthe Z axis based on, least, the associated time coordinate 963A-N of therespective initial depth image 961A-N includes the following functions.Tracking, via the inertial measurement unit 972, a head orientation of ahead of a wearer of the eyewear device 100. The wearer of the eyeweardevice 100 is the user that is actually creating the warped shockwavevideo 964 on a mobile device 990 or a different user that wore theeyewear device 100 when the initial video 960 was generated. Based onthe head orientation, determining a floor plane of vertices which arecontiguous along the Z axis of the respective initial depth image961A-N.

Such location coordinates can be transmitted to the eyeweardevice over one or more network connections via XCVRs 1010, 1020.

The transceivers 1010, 1020 (network communication interface) conformsto one or more of the various digital wireless communication standardsutilized by modern mobile networks. Examples of WWAN transceivers 1010include (but are not limited to) transceivers configured to operate inaccordance with Code Division Multiple Access (CDMA) and 3rd GenerationPartnership Project (3GPP) network technologies including, for exampleand without limitation, 3GPP type 2 (or 3GPP2) and LTE, at timesreferred to as “4G.” For example, the transceivers 1010, 1020 providetwo-way wireless communication of information including digitized audiosignals, still image and video signals, web page information for displayas well as web related inputs, and various types of mobile messagecommunications to/from the mobile device 990 for shockwave creation.

Several of these types of communications through the transceivers 1010,1020 and a network, as discussed previously, relate to protocols andprocedures in support of communications with the eyewear device 100 orthe server system 998 for shockwave creation, such as transmitting leftraw image 858A, right raw image 858B, infrared image 859, initial video960, initial depth images 961A-N, time coordinates 963A-N, warpedshockwave video 964, and warped shockwave images 967A-N. Suchcommunications, for example, may transport packet data via the shortrange XCVRs 1020 over the wireless connections 925 and 937 to and fromthe eyewear device 100 as shown in FIG. 9. Such communications, forexample, may also transport data utilizing IP packet data transport viathe WWAN XCVRs 1010 over the network (e.g., Internet) 995 shown in FIG.9. Both WWAN XCVRs 1010 and short range XCVRs 1020 connect through radiofrequency (RF) send-and-receive amplifiers (not shown) to an associatedantenna (not shown).

The mobile device 990 further includes a microprocessor, shown as CPU1030, sometimes referred to herein as the host controller. A processoris a circuit having elements structured and arranged to perform one ormore processing functions, typically various data processing functions.Although discrete logic components could be used, the examples utilizecomponents forming a programmable CPU. A microprocessor for exampleincludes one or more integrated circuit (IC) chips incorporating theelectronic elements to perform the functions of the CPU. The processor1030, for example, may be based on any known or available microprocessorarchitecture, such as a Reduced Instruction Set Computing (RISC) usingan ARM architecture, as commonly used today in mobile devices and otherportable electronic devices. Of course, other processor circuitry may beused to form the CPU 1030 or processor hardware in smartphone, laptopcomputer, and tablet.

The microprocessor 1030 serves as a programmable host controller for themobile device 990 by configuring the mobile device 990 to performvarious operations, for example, in accordance with instructions orprogramming executable by processor 1030. For example, such operationsmay include various general operations of the mobile device, as well asoperations related to the shockwave creation programming 945 andcommunications with the eyewear device 100 and server system 998.Although a processor may be configured by use of hardwired logic,typical processors in mobile devices are general processing circuitsconfigured by execution of programming.

The mobile device 990 includes a memory or storage device system, forstoring data and programming. In the example, the memory system mayinclude a flash memory 1040A and a random access memory (RAM) 1040B. TheRAM 1040B serves as short term storage for instructions and data beinghandled by the processor 1030, e.g. as a working data processing memory.The flash memory 1040A typically provides longer term storage.

Hence, in the example of mobile device 990, the flash memory 1040A isused to store programming or instructions for execution by the processor1030. Depending on the type of device, the mobile device 990 stores andruns a mobile operating system through which specific applications,including shockwave creation programming 945, are executed.Applications, such as the shockwave creation programming 945, may be anative application, a hybrid application, or a web application (e.g., adynamic web page executed by a web browser) that runs on mobile device990 to create the warped shockwave video 964 from the initial video 960based on the received shockwave effect selection 962. Examples of mobileoperating systems include Google Android, Apple iOS (I-Phone or iPaddevices), Windows Mobile, Amazon Fire OS, RIM BlackBerry operatingsystem, or the like.

It will be understood that the mobile device 990 is just one type ofhost computer in the virtual shockwave creation system 900 and thatother arrangements may be utilized. For example, a server system 998,such as that shown in FIG. 9, may create shockwaves in the initial video960 after generation of the initial depth images 961A-N, via thedepth-capturing camera of the eyewear device 100.

FIG. 11 is a flowchart of a method with steps that can be implemented inthe virtual shockwave creation system 900 to apply shockwaves to theinitial depth images 961A-N from the initial video 960 to generate thewarped shockwave images 967A-N to create the warped shockwave video 965.Because the blocks of FIG. 11 were already explained in detailpreviously, repetition of all of the details is avoided here.

Beginning in block 1100, the method includes generating, via thedepth-capturing camera, a sequence of initial depth images 961A-N frominitial images 957A-N of an initial video 960.

Proceeding now to block 1110, the method further includes determining,for each of the initial depth images 961A-N, a respective rotationmatrix 973A-N. The respective rotation matrix 973A-N is to adjust X, Y,and/or Z location coordinates of the vertices based on detected rotationof the depth-capturing camera. For example, the rotation matrix 973A-Ncan be a 2×2 or 3×3 matrix with X, Y, and/or Z axis position adjustmentsor angles to normalize the vertices in the captured initial depth images961A-N with the floor plane to correct for camera rotation.

Continuing to block 1120, the method further includes generating, foreach of the initial depth images 961A-N, a respective warped shockwaveimage 967A-N by applying the respective rotation matrix 973A-N and thetransformation function 965 to vertices of a respective initial depthimage 961A-N. The transformation function 965 transforms a respectiveshockwave region of vertices 966A-N grouped together along a Z axisbased on, at least, the associated time coordinate 963A-N of therespective initial depth image 961A-N. The transformation function 965moves a respective Y location coordinate of vertices in the respectiveshockwave region of vertices 966A-N vertically upwards or downwards onthe Y axis based on a wave pattern 971. Moving now to block 1130, themethod further includes creating, a warped shockwave video 964 includingthe sequence of the generated warped shockwave images 967A-N.

Finishing now in block 1140, the method further includes presenting, viaan image display 180A-B or 1080, the warped shockwave video 964. Thestep of presenting via the image display 180A-B or 1080, the warpedshockwave video 964 including the sequence of the generated warpedshockwave images 967A-N presents an appearance of a rolling waveradially from the depth-capturing camera, radially from an objectemitting a shockwave, or along a Z axis of the warped shockwave images967A-N of the warped shockwave video 964.

FIGS. 12A-B illustrate an example of a first raw image 858A captured byone of the visible light cameras 114A-B and application of atransformation function 965 to a first shockwave region of vertices 966Aof a generated first initial depth image 961A, respectively. A firsttime coordinate 963A set to 0.00 seconds is associated with the firstraw image 858A during capture, and therefore the corresponding firstinitial depth image 961A and the first shockwave depth image 967A arealso associated with the first time coordinate 963A of 0.00 seconds. InFIG. 12A, the first raw image 858A is depicted as captured by one of thevisible light cameras 114A-B before any image processing (e.g.,rectification, etc.). Thus, the first raw image 858A has a fish eyeappearance, resulting from vignetting by the visible light camera114A-B. The first raw image 858A includes various two-dimensional pixelswith X and Y location coordinates on an X axis 1205 and a Y axis 1210.The corresponding first initial depth image of 961A of the sequence ofinitial depth images 961A-N in the initial video 960 is subsequentlygenerated using techniques described previously. In FIG. 12B, a Z axis1215 is depicted as being overlaid on the generated first shockwavedepth image 967A of the created warped shockwave video 964. A floorplane 1220 of the first shockwave depth image 967A is contiguous alongthe Z axis 1215. In addition to the orientation sensor techniquesdisclosed above (e.g., utilizing an inertial measurement unit 972) toidentify the floor plane 1220, a heuristic can be utilized that assumesthe floor plane 1220 is somewhere between 5 feet and 6 feet from thevertical position of the depth-capturing camera that generated the firstinitial depth image 961A. This assumes a human of average height worethe eyewear device 100 when the first raw image 858A was captured anddid not skew or rotate his/her head. In this instance, the person wasstanding five to six feet above floor level (e.g., ground level). InFIG. 12B, the application of the first transformation function 965A onthe first shockwave region 966A is depicted, and this results inshockwaves which appear to be in the near range as a result of the firstshockwave region 966A being in close range (e.g., short depth/distance)on the Z axis 1215.

Asecond time coordinate 963B set to 0.25 seconds is associated with thesecond raw image 858B during capture, and therefore the correspondingsecond initial depth image 961B from the initial video 960 and thesecond shockwave depth image 967B of the warped shockwave video 964 arealso associated with the second time coordinate 963B of 0.25 seconds. InFIG. 13B, the application of the second transformation function 965B onthe second shockwave region 966B is depicted, and this results inshockwaves which appear to be in the intermediate range as a result ofthe second shockwave region 966B being in intermediate range (e.g.,medium depth/distance) on the Z axis 1215.

FIGS. 14A-B illustrate an example of a third raw image 858C captured byone of the visible light cameras 114A-B and application of thetransformation function 965 to a third shockwave region of vertices 966Cof a generated third initial depth image 961C, respectively. A thirdtime coordinate 963B set to 0.50 seconds is associated with the thirdraw image 858C during capture, and therefore the corresponding thirdinitial depth image 961C from the initial video 960 and the thirdshockwave depth image 967C of the warped shockwave video 964 are alsoassociated with the third time coordinate 963B of 0.50 seconds. In FIG.14B, the third shockwave region 966C is depicted, but no shockwavesappear because the third shockwave region 966C either: is no longer onthe floor plane 1220; or reaches an ending depth position on the Z axis1215.

FIGS. 15A-B illustrate an example of a fourth raw image 858D captured byone of the visible light cameras 114A-B and application of thetransformation function 965 to a fourth shockwave region of vertices966D of a generated fourth initial depth image 961D, respectively. Afourth time coordinate 963D set to 0.75 seconds is associated with thefourth raw image 858D during capture, and therefore the correspondingfourth initial depth image 961D from the initial video 960 and thefourth shockwave depth image 967D of the warped shockwave video 964 arealso associated with the fourth time coordinate 963D of 0.75 seconds. InFIG. 15B, the application of the fourth transformation function 965D onthe fourth shockwave region 966D is depicted, and this results inshockwaves which appear to be in the near range as a result of thefourth shockwave region 966D being in near range (e.g., shortdepth/distance) on the Z axis 1215.

FIGS. 16A-B illustrate an example of a fifth raw image 858E captured byone of the visible light cameras 114A-B and application of thetransformation function 965 to a fifth shockwave region of vertices 966Eof a generated fifth initial depth image 961E, respectively. A fifthtime coordinate 963E set to 1.00 seconds is associated with the fifthraw image 858E during capture, and therefore the corresponding fifthinitial depth image 961E from the initial video 960 and the fifthshockwave depth image 967E of the warped shockwave video 964 are alsoassociated with the fifth time coordinate 963E of 1.00 seconds. In FIG.16B, the application of the fifth transformation function 965E on thefifth shockwave region 966E is depicted, and this results in shockwaveswhich appear to be in the intermediate range as a result of the fifthshockwave region 966E being in intermediate range (e.g., mediumdepth/distance) on the Z axis 1215.

A sixthtime coordinate 963F set to 1.25 seconds is associated with the sixthraw image 858F during capture, and therefore the corresponding sixthinitial depth image 961F from the initial video 960 and the sixthshockwave depth image 967F of the warped shockwave video 964 are alsoassociated with the sixth time coordinate 963F of 1.25 seconds. In FIG.17B, the application of the sixth transformation function 965F on thesixth shockwave region 966F is depicted, and this results in shockwaveswhich appear to be in the far range as a result of the sixth shockwaveregion 966F being in far range (e.g., long depth/distance) on the Z axis1215.

Aseventh time coordinate 963G set to 1.50 seconds is associated with theseventh raw image 858G during capture, and therefore the correspondingseventh initial depth image 961G from the initial video 960 and theseventh shockwave depth image 967G of the warped shockwave video 964 arealso associated with the seventh time coordinate 963G of 1.50 seconds.In FIG. 18B, the application of the seventh transformation function 965Gon the seventh shockwave region 966G is depicted, and this results inshockwaves which appear to be in the farthest range as a result of theseventh shockwave region 966G being in very far range (e.g., maximumdepth/distance) on the Z axis 1215.
